Description
Technical Field
The invention belongs to preparation and application of interface heat conduction materials, and particularly relates to a preparation method of a two-component heat conduction gel capable of being rapidly cured at room temperature.
Background
The interface heat conduction material plays an extremely important role in the fields of electronics, electricity, aviation, aerospace and other manufacturing industries and high technology. The heat-conducting gasket has excellent ageing resistance and oil separation resistance, so the market mainly takes the heat-conducting gasket as a main material. However, with the rapid development of the miniaturization of electronic equipment, the internal structure of the device is more and more complex, and the operable space is smaller and smaller, the traditional heat conducting gasket is difficult to meet the requirements due to the processing precision and the manual operation space, and at the moment, the heat conducting gel with better fluidity is required to meet the heat dissipation requirements of the special-shaped structure and the small space.
The two-component heat-conducting gel has the advantages of convenient construction and almost all the advantages of a heat-conducting gasket after being cured. However, the curing modes of the current two-component heat-conducting gel are all temperature-rising curing (>100 ℃), but some electronic components do not have the high-temperature-resistant condition. However, the curing time of the two-component heat-conducting gel at room temperature is very long, more than 24 hours are basically needed to achieve complete curing, and the fluidity of the gel in the curing process can cause pollution of the gel to other devices. While increasing the amount of catalyst in the system can reduce cure time, the effect is limited. The main reason is that the surface of the filler powder has a large amount of metal ions such as sodium, potassium and the like, and the existence of the metal ions can inhibit the activity of the catalyst. In the high heat conduction product, the proportion of the powder in the system is more than 90 percent, even more than 95 percent, and the influence of the metal ions on the surface of the powder on the catalyst is more obvious. In addition, the aging resistance of the system is greatly affected by the excessive dosage of the catalyst, and the service life of the product is greatly reduced as a result.
